Late 90s Jap model would get my money
As long as they have been well looked after/serviced, I have had mixed luck with old Jap cars, engines seem to out last everything that is bolted to them 😉
My banger funds have gone up over the years from 1k to anything up to 2k, but some of the best runners I have had in the past have all been motorway high milers, stuff most wont touch because the miles dial puts most off.
latest banger for me, mk4 golf tdi estate, often overlooked by the masses in favor of the passat estate and yes there are better cars out there for the money I am sure, I paid £1500, milage supersonic, avg. 49mpg since I have owned it on school runs and short trips.
Number of owners can be a better indicator of condition sometimes I find 😉
