Well the Nissan Trad Sunny is newer of the lot I mentioned and it has a solid reputation ,also if your lucky you will get the one with power steering as well ,there are different trim levels and all apart from the last are all Carburetor models, last model had one trim level with efi but those are very very rare and also out of your budget (do remember to keep aside 300K for repairs when you buy 2nd hand cars)
I used the Lancer A72 car and the C12 Lancer saloon ,of these the A72 came out tops,C12 though better looking is not as hardy
The Lancer Box sadly eluded me so I could not own one, but know ppl who owned and they are very good and comfy
BUT as all others said a car this old is only as good as how it was maintained and I would humbly ask you to take someone really knowledgeable about cars this old when you go to see them if not your asking for trouble
I will also advice you to Avoid cars such Daewoo,Hyundai Stellar,Hyundai Pony,Mitsubishi Tredia (lack of parts and most are hacked out) as well as Daihatsu Charades and the 11 or 12 Sri Ford Laser/Mazda 3232 (lots of them have been raced and hacked out)so stay clear of them
Good luck and please keep us posted!
