x2 what Shaun N said... (mostly)...
I own and have owned higher mileage cars. Obviously buy one that has been cared for and not hacked on is imperative if you're going to enjoy your TR ownership experience. My current tr cars are 73k and 89k respectively and have absolutely zero issues (for sale too). They're not beat on or abused and are super reliable. The last one I sold had been used as a DD in SoCal and had over 160k. I can tell you that this car was DRIVEN and cared for meticulously.
My preference is to avoid wiring hacks and basket cases that are other people's headaches. And I take a hard pass on too many mods or "colorful" set ups. If a kid (who doesn't know what they're doing) has been in there messing with things I'm not interested... Kinda like my dd honda that I purchased from an adult. It had 150k on in and now has 244k and is still going strong. I paid a little more but I didn't get some riced out POS either. My other dd has 180k- also no issues.
Now, I know that there are a few guys floating around that buy modded cars and de-mod them and return them to stock. What I don't like is when people do this and try to pass the car off as never modded (ie: all original, unmolested). Buyer beware on that score. I have a pretty good idea what stock should look like and can usually tell if something is amiss. Just a heads up for you if you're in the market.
Honestly, after owning "higher mile" cars, I wouldn't bat an eye looking at 120k + miles on a car. My 73k and 89k mile cars are lower mile cars in my opinion. (In nearly 30 years to have amassed 89k miles you'd have to drive almost 3k a year!
) Of course there's the ultra low mile stuff (under 50k) but I'd kinda feel guilty putting miles or modding a car that has been preserved.
Just my .02
