wow 18K on an almost 10 year old car is purty good. You should have a pretty low monthly payment.
Funny thing is my old Miata had about 50% of purchase value in mostly performnace modifications. Had allot of fun with it and ended up getting nearly all my money back when I sold it to some die hard Miata guy. When I got the Boxster I did nothing to it in terms of performance mods and I'm still 100% satisfied with the peformance. The only performance mod I would consider is a cooler sounding exhaust but I don't consider that a REAL performance mod.
And I only buy upgrades I can sell after the fact. I hold onto all my stock parts, I might even remove the side skirts! LOL. Althoug in all honesty...I may never sell this car. The money I can get for it just will not be worth parting with it.
I have a feeling I will end up owning my BoxsterS (summer), a bargain 996 C4S(winter)a Prius (daily driver)and the new
track ready RS styled Mini CooperS seems like its right up my alley.
