i ll not favor it. there are number of cons.
1- your cars will be badly abused and may need an engine overhaul even in a year.
2-there are always some accidents which will lower the resale of your car.
3-dealers always delay payment.
4-God forbid if your car gets stolen.
5-dealers replace original and new components of your car.
these are some of many cons
in the end it will be you who lose and not the dealer.
