i was like wtf!! when it u said u bought it for 3k, but then i found out it did 490000ks lol.
strange that ur car didnt have aircon. mine was a 1,3l engine and it HAD aircon =]
as for moding, dont do anything to the car. dont do a service dont do anything to it. save ur money. drive it till it dies then change to an EFI engine. best tihng u can give ur baby.

btw: looks good except for that front right fender. hehe
