I've had a 2011 Scion tC since I was 16, I am now 19. Monthly insurance is astronomical despite never having been in an accident or pulled over, it's slow, rides like an old WRX on cheap coilivers, it's noisy, interior pieces rattle, and overall feels cheap and flimsy. 16-year-old me bought it on the promise of reliability, but I've encountered a string of failures and issues which, when combined with my indifference toward the car as a whole now, have left me wanting something else.

I want something either faster and sportier (probably not a wise idea, given the already high insurance costs for any sort of enthusiast car for someone of my age), or quieter and more comfortable. I don't beat on cars, I'm not interested in modifications at this point, and I'm more than willing to invest in preventive measures to stop rust or known failures.

I've seen and heard nothing but good things about LS430s, and this one popped up at a small dealership 10 minutes from my house. It has 186,000 miles (the Scion is at just shy of 110,000), the list price is half as much as I paid for the Scion in 2022 and considerably less than it's worth now, and I know a good shop three minutes away that could do a PPI.

Would selling my 15-year-old Scion for a 25-year-old Lexus be a bad idea? What should I look out for? Would service and maintenance be prohibitivly more expensive? Does the air suspension on these LSs fail as as frequently as on 2000s S-classes? Advice is much appreciated.

Should I buy a Lexus LS430?
