is 1500 kg the trailer capacity or does outfit actually weigh that much if it does then you really need a vehicle that weighs about 2000kg so you're into 4X4 territory Ideally the towed outfit should weigh approx 75% of the car personally I would go for a bmw 320 or 520 diesel ( trailer weight permitting) both rear wheel drive and enough torque to do pull up most slipways but no good off the beach + you get 40 - 50 mpg solo. There's no doubt the 4X4s are better tow cars but how much time do you spend towing?
And before Codprawn starts I'd love a Disco, but do i want to live with one everyday of the week? yes please
Incidentally I have been offered a T reg grand Cherokee 4.7 V8 petrol has anyone any views on this?
