1st gen Corvair is very "of the moment" stylewise.
2nd gen GM could use the exact exterior (with modern fittings) on a new EV and it would not only look current today, but also be better looking than 99% of EV and concept EV.
The second gen Corvair can easily challenge the best styling from Italy.
I saw a 4 door hard top sedan last week that look almost as good as the coupe.
It was the color my fathers was and had bumper guards like dads. Then I looked inside and it was a 4 speed sedan. Never saw one like that before,
Engineers and designers often got overruled as well. What those in charge think the people want (with a dash of compliance at times) muddies things up.
Look how many people swap out the 70s 5mph bumpers for earlier versions (if they exist for their vehicle).
Many cars would have been much lower from the factory if it was up to the designers.
Most 50s and 60s cars would have been chopped 3-6 inches from the factory if you look at the actual concept drawings. Production model had to fit "tall man with big hat".
Thin sidewall tires ride harder, but depends where you are driving. More contact patch is more racy. I prefer cushy ride so no elastic band tires for me. We swapped them off of a late model vehicle we had for this very reason. Didn't come factory with the smaller diameter rim and tall sidewall but fit perfect.
Exhaust note... I am the rare person (apparently) that had my loud muffler my Mustang came with swapped out for a much quieter one.
Most of these things (that you can easily swap) come down to personal choice. Sure some of the choices may cause some earlier wear, but if you are actually using the vehicle then wearing it out should be the goal.
You can always restore it again and revert it to stock if you want to.
I predict that if you buy a set of 2022 tires they will not last 28 years no matter how lightly you use them.
Then again, I could just be wearing a tinfoil and steel-belted hat.
If you have a newer turbo car the best thing I ever did was add a tune to it.
GM offered a tune for my 2.0 engine. It added 65 hp and never voided the warranty.
I did have to use premium due to the 23 psi of boost but it added 1-2 mpg too.
It totally transformed the car and in 10 years nary a mechanical issue.
Tunes are great but be sure to study them and make sure to buy a reliable well sorted one.
I did all this for less than $300.
It's patina. Cover it with coat of semi-gloss!
I jest, but people should only sweat the appearance details if the details matter to them.
