Hi guys, Ive narrowed down my search to two pre-owned brzs
(1) 2013 BRZ ran 8,500 miles (mostly city traffic)
- very low mileage, complete service records
- only cons are - owner doesnt seem to take good care of the interior. Scratches everywhere, left under the sun, smoked a bit. I know its fixable but my fear is the lack of interior care may also translate to a lack of general car / driving care.
(2) 2014 BRZ ran 20,000 miles already (plenty of highway miles, i would estimate this car ran 8,500 city and 12,000 highway in total.
- upgraded rims to 18 but all stock rims included
- rest of car is bone stock except for better floor mats, trunk mats, and wurth underbody.
- also complete service records

Although the second unit seems like the better choice espnwith a more OC owner, ive never purchased a used car thats relatively young with this much mileage. (Im from the philippines, and most cars here should be considered 10,000 miles
Below to be good preowned) how much life can i get from a regularly maintained 20,000 mile unit?

A. Am i seeing parts replacements anytime soon?
B. At 20,000 miles, is the engine for example less efficient or i wont get to enjoy its full potential as brand new anymore?
