As you have experience of Suzuki cars and their G series engines, i think Margalla will be better options as (if i am right) a good Baleno will be about 1-1.5 Lakh expensive than your budget. You might get Baleno in this price but i highly doubt it will be in good condition so go for a well maintained Margalla as you want bigger boot space (diggi) so Cultus is not an option. Keep one thing in mind while buying old cars. There will be maintenance works that you will have to do on older cars either immediately or within few months so never compromise on body condition. You can change tires in around 12-15k engine, gear everything in around 1 Lakh (if needed) but if cars body (doors, columns,floor,engine bay etc are rusted or damaged, then its becomes very difficult. So get a Margalla in good condition. Maintenance cost for margalla and cultus is almost same as both are same cars basicaly, just cultus is hathchback and margallah is its sedan. Parts are easily available (not as easy as mehrans parts but easily). Resale is not very bad but not very good too for Margalla. Performance of AC in such old cars is doubtful as even new AC unit is installed, compressor puts load on engine and engine being 20 years old heats up so don't expect trouble free, chilled AC in old cars. I don't have any idea about mileage.
