I passed a sweet looking '72(?) Dart on the freeway today with four young guys cruising, windows down, just enjoying another gorgeous day in paradise (It's 75 degrees, today, not a cloud in the sky.) Metallic copper brown with a white bumblebee stripe, dog dishes and you know it had the leaning tower of power under the hood.
Other Mopars:
Another '71-74 Satellite four-door with a 318, like the one I owned in the early 90's. Mine looked just like the one in the photo, except it was beat up.
A 60's B-body wagon. That '63 330 that George (toomanyprojects) is selling is way cool!
http://www.cuda-challenger.com/cc/index.php?topic=54372.0Not really low powered, but a mid-60's C-body convertible with a 361 or 383 would be a cool cruiser.
A slant-six or 318 68-69 Barracuda, preferably with a manual transmission.
A late-60's/early 70's D200 crewcab 4x4
Others:
I have one of them - my '87 Civic is a great little around-town daily driver - light, agile, zippy, economical but not near fast enough to get in trouble. I'd love to get a later-model Civic to turn into a good roadrace or autocross car. I'd convert mine, but there isn't much in the way of performance parts for the 3G Civics.
I like the late-60's Mustangs. A 289 or 302 powered stocker would be cool.
When I was a kid, my mom had two cars that I really liked. We had a 1964 Nova station wagon with the six in it. Those early Nova/Chevy II's are way cool.
The other was a '71 VW bus that I learned how to drive a stickshift in. I'd like to have either a Westfalia camper or a '60s 21 window van. I don't know if I'd want to keep the stock engine though - a little too underpowered.
