That.
Pre-2001.5 cars had a bosch MAFS and they go bad more often than the Hitachi. I had a bosch on mine for ~120k miles and it still did not go bad, I had to upgrade to the hitachi when I went stage 3.
At 80k miles you are coming up to timing belt time, very important. It will be pricey if you take it somewhere to have it done. Pretty easy and real cheap to do it by yourself. I replaced my front suspension at around 110k because I had a couple of bad balljoints, those are pretty common too.
The center display are bad in almost all cars (I replaced mine). Diverter valves and throttle body boots need to be replaced when you chip the car. Its not a matter of "if" but "when" the turbos will blow if they arent taken care of.
I had 3 axle boots tear on me (all of them were front axles), in a time span of about a year or 2. I dont think they like being on a lowered car.
OEM valve cover gaskets like to leak. I had my first wheel bearing go bad at around 120k miles.
You need to find one thats been taken care of or you will have to fix the PITA/Pricey things ie Turbo, Syncros, Heads (if the timing belt fails).
I warn you, you will not have your cobra long after you get an S4
