These cars are quite simply built - they have some oddities like the boot has rails IN the boot and the underside of the car is flat - the exhaust muffler is mounted under the right rear passenger seat. Spare wheel has a belt to hold it because there is no round cavity in the boot - its huge and flat.
Body parts for this car are a nightmare in Pakistan as there was never a proper dealership for these, Mechanical parts for engine are very simple - they dont wear out that much but are not hard to source, the other mechanical parts like bushings, shocks, steering rack, link rods, tie rods, ball joints CV joints etc would be a bit more expensive due to lack of availability.
