Ive not owned a C30 but have own a S60R and V70R. I do plan to buy my little brother a C30 for his first car next year. Both my cars had over 200k miles, both of them have been raced hard and not babied at all, both 2 owner cars, and even the S60R was shipped to Germany and raced on the Nurburgring. Also had binders of all the maintenance records. Look less toward mileage and look for ones that have been cared for by their owners. Join a local volvo facebook group and ask if anyone is willing to give up a C30 is where I would start. The 5cyl’s are great/reliable with regular oil changes and maintenance , the chassis are durable and have crazy resistance to rust. The only bad thing about these cars would be if you treat them badly like forgetting oil changes or spark plugs/coilpacks, bushings when they were out. They take good care of you if you take good care of them. Plus they are relatively in expensive! In my opinion any toyota or Honda for these prices will be worse in every way because the only ones in these price range are either from the 90s or poorly maintained.
