What late model accessories do you wish your old car had?

think i'm going to try a shoulder / lap system in my next project.
As for the wish lists..
instead of A/C and power windows maybe white or pearl interior will keep you cool enough
instead of O/D try 2.94 gears and a 904 with the 1st and 2nd gears from a lock up piece for mpg
also for better mileage and a strong launch a short duration stock style cam will help
for better chassis stock mopar upgrades with bars, springs, shocks and radial tires will help some
stock disc front and rear drum are fine if in good repair..rear discs will not be a big gain.
If you're not a quarter miler a quieter stock style exhaust and 2.94 or 3.23 gears are cruising pleasure.
But there's no denying it...like everyone else the new vehicles have me spoiled! My stock 340 is probably 275 hp and there are minivans with over 300hp.My friends Grand Cherokee Jeep is 485 hp..sheeesh!
