Let me try to look at it with cold hard logic
Your primary needs are: resale value, rear seat comfort, powerful engine, good a.s.s within 15L OTR. No Tata, No Hyundai, No HM,No Ford.
Rear seat comfort & powerful engine are characteristics of the car itself. With these parameters, your choice narrows down to
a. Magnum
b. Corolla
c. SX4
d. Civic
Comfort - IMO, Magnum is the best
Engine - Your dad will probably love the 30+ torque of the magnum against the corolla civic petrols. After all if he needs some petrol adrenaline rush, the 1.8TPi option is always there. Plus I don't think the SX4 will thrill him. The only problem with the Magnum seems to be turbo lag during city driving. But most of the rush hour driving will be taken care of by the driver.
Now lets come to
A.S.S
GM has two dealerships
Toyota has one
Honda now has two
SX4 has five + MASS's.
Haven't heard of major horror stories (a.k.a Ford) for any of them. For GM, a colleague of mine who drives a Corsa, is pretty impressed with their responsiveness. You could also check with @Hells Bells (Aveo). Convenience wise Toyota is pretty far from your home, right ? GM, MUL are nearby. Windor Honda is faar away. Imperial should be nearby.
Finally lets do some
mooolah calculation.
Mileage covered in 3yrs - 1000*12*3 + 2000*6 = 48000kms
(1000 every month for 3yrs + 6 trips of 2000kms each)
Assume avg petrol car mileage of 10kmpl
Assume avg diesel car mileage of 13kmpl
Cost of premium petrol for 3 yrs - (48000/10)*48.5 = 2,32,800
Cost of premium diesel for 3 yrs - (48000/13)*33.5 = 1,23,692
Fuel savings - 1,09,107
SX4 ZXi
OTR - 7,60,000
Resale loss - 3,04,000 (Assumed depreciation of 40%)
Petrol + Loss =
5,36,800 Corolla
OTR - 11,00,000 (approx, not top end)
Resale loss - 3,85,000 (Assumed depreciation of 35%)
Petrol + Loss =
6,17,800 Civic S Manual
OTR - 12,00,000
Resale loss - 4,20,000 (Assumed depreciation of 35%)
Petrol + Loss =
6,52,800 Magnum (top end with ABS Airbags)
OTR - 10,80,000
Resale loss - 4,86,000 (Assumed depreciation of 45%)
Diesel + Loss =
6,09,692
GM has free maintenance for 3yrs. Toyota also has this ? Not sure. MUL & Honda don't.
IMO, it boils down to the SX4, if petrol else the Magnum. If you let the head rule over the heart it makes sense to have an oil burner offset the expenditure of ripping the TPi.
Chalo lets go take a TD of both
