Stretch? Knight Rider was pretty much just a re-make of The Dukes of Hazzard.
White Collar has a little of this feel. No cool vehicles, but Neal is basically a superhero. Well, super-anti-hero. And there are arcs where he’s basically a criminal…
Burn Notice is kind of in the vein, but the arc stories get very grim. Michael works for a couple of stone sociopaths at various points. So, not quite the same thematically.
I think the real answer to the OP is TV has switched from freelance vehicular based crime fighters to historic adventurers.
There was the obvious Hercules (1995) and then the spin off Xena: Warrior Princess.
Since then there have been that dreadful South African production of The Adventures of Sinbad (1996) plus the more recent UK/USA Sinbad of 2012.
There has been that Da Vinci show, the Pirates show (Black Sails), The (Three) Musketeers, Robin Hood variants, King Arthur variants (Merlin for example), Atlantis and so on and so on. Most are short lived.
They tend to have clear cut good guys and bad guys battling to appeal to the children plus there is usually a well upholstered female for the Dads.

The one with that guy from Leverage? And the chick from King and Maxwell? 
We wondered if we should be watching that.
Other than that a lot of the story lines revolved around an indestructible super-car, I’d call that a stretch. You might as well equate KITT and the A-Team’s van.
Yep, Burn Notice always reminded me of 80s action shows. Especially Magnum PI.
Good one. I think that’s a good fit.
I’m anticipating a few new shows to return to this style. Recent attempts like Intelligence, Nikita, Almost Human, and Covert Affairs are in that vein too, and though they didn’t all succeed, they still have enough appeal for the genre to keep being resurrected.
Grimm is a show I’d have totally dug as a kid. *Constantine *is probably a bit dark for a 9-14 year old boy though.
I’d have liked Burn Notice too- it’s the closest thing to the A-Team / Magnum PI style of show that I can think of in recent years.
I imagine NCIS, Agent Carter and *Scorpion *might be something a boy might like also. Really any of the comic-related shows- Agents of SHIELD, *Arrow *and The Flash come to mind.
I haven’t watched the show, but I’ve seen several trailers for Justified, which seems to be a show about a small town Sheriff “enforcing his own brand of justice”.
The Highwayman had a helicopter but it was rarely seen separate from his truck.
To answer the OP: look for Walker, Texas Ranger, especially season 5 and later.
There was Nightboat, but it was rendered implausible due to the unrealistic number of convenient canals 
I’m pretty sure you don’t want the kids watching Black Sails. There’s an awful lot of exposed upholstery. Might be in some of the others as well – I don’t know them all.
What about all the superhero/comic shows on these days? Arrow, Flash, Agents of Shield, etc? [Edit: I see Bump already had this same idea]
I’ve thought the same thing, and PoI is also a bit like Quantum Leap.
I will say that PoI has a pretty good ongoing storyline too though, it’s more than just a “save the person of the week and never see them again” show.
My fault. Never watched Black Sails, just seen trailers for it and knew it had pirates.
Luckily I managed to avoid mentioning the various Spartacus shows which I have watched, and actually enjoyed (Why yes, Captain, I DO enjoy watching shows about gladiators and sorry if I called you Shirley) and so realised the upholstery exposed, plus the ferocious language plus the CGI enhanced violence would probably rule them out.

That’s sort of the underlying trope, but it has almost nothing to do with the actual show. It’s right and wrong at the same time.
Justfied = the show where Walton Goggins does not have a great rack.
Ok, thanks.
Since Riptide was mentioned early I’ll submit Supernatural. Two brothers driving back and forth across the country in an black 67 Impala.
Actually, rereading the OP, 10 and 12 are a little young for Supernatural.
Yeah, Supernatural is a great show, but they’re fairly unrestrained (for network TV anyway) with the blood. There’s also some language that some parents might not be comfortable with, particularly they seem to throw around “dick” a lot more than any other non-cable show I’ve seen.
As for the superhero shows, [ul]
[li]I’d say Flash would probably be most kid friendly. [/li][li]Arrow’s okay, but sometimes gets a little dark (and was more so when it started, before they apparently decided to go more superheroey than they first planned). [/li][li]Agents of SHIELD is really more for that snarky adolescent (and snarky adolescent at heart) demographic that Joss Whedon is known for (even if he’s not super involved, it’s very much his sort of show in tone). Young kids might not even appreciate it if they did watch it.[/li][li]Gotham is very dark, darker even than the Batman Begins trilogy, which a lot of people didn’t want their kids to watch.[/li][li]Constantine, definitely not kid friendly, but it’s based on a comic made for adults, so that’s to be expected.[/li][/ul]
They were the Pulp Magazine Heroes of TV.
They had lots in common with Doc Savage, or the Shadow.
Hell, I’m in Dallas at some comicon and there’s the Supernatural car with people paying perfectly good money to have their pictures taken with it. 
Before yesterday, I didn’t even know there was a car involved in the show.
