It doesn't have to be a real production car, it can also be a concept.
For me, it has to be the 1997 Dodge Copperhead. This ugly chungus just speaks to me and I don't know why. It is hideous, Pontiac Aztek levels of ugly, but I kinda wish Dodge actually sold it. It wasn't going to be gutless, sharing much with the Viper, but it also wasn't going to have the same price of the Viper (Viper at the time was ~$75k, this baby would have been ~$30k). For the price, a little ugly isn't that big of a deal for a similar powertrain. Surely a facelift kit could help it out some.
Just thought a discussion like this could be fun. What cars are the same for you?
We had two different Lumina vans. Both with the 3.1. It wasn't fast but it did ok. The first was traded for the second which was the later snub nose version. It didn't hold well. Torque converter died, mom paid too much to have it replaced. The inside was pretty rattly and then the power steering died, ate the serpentine belt and the local shop said it was probably not worth fixing since the AC was also dead. RIP u-body. It was good while it lasted but it was of modest quality. I miss wierd cars.
I new an engineer working for GM as a co op student and even before they started selling it they were called the Lemona.
The line was entirely designed by accountants.
And people wonder when I say GM never made good cars...
