[Gator328i]

I'm facing a decision and I'd be interested to get some opinions:

My 328i is paid off so I'm tempted to take 5 grand and add a BMW performance exhaust, new set of 18" wheels, and BMW performance suspension to it.

On the other hand, I could take that 5 grand and put it towards a CPO 335, but then I'm stuck with payments for 3 or 4 years.

By modifying the 328, I get a nice, but underpowered, customized car exactly how I want it free and clear.

By buying a CPO 335, I get a more powerful car that will basically have all the upgrades I would have added to the 328, plus 70 more bhp and 100 more lbs/ft of torque. But then of course I'm back to cracking that nut every month.

What's the better way to go?
