It might have been a bit extra but you really need to understand how they work. Jake Wright's are a Land Rover Specialists - they're enthusiasts just like you and I, Diller's simply buy and sell. That extra couple of thousand would have certainly been poured into the motor, not just slapped on top. They run through absolutely everything: The chassis, engine, drive train, electrics, interior etc. all meticulously scrutinised. If something isnt quite right, it'll be put right and put right to last. Everything will be serviced from the axle oils and the timing belt to air conditioning and coolant, not just an engine oil change or a fuel filter. They also give a pretty good warrenty and their aftercare is excellent. I dont know if as much can be said for Dillers. Jesus it sounds like I'm in sales! Perhaps they'll offer me a job!?
I'm just a happy customer. Take a trip down to see them if you haven't already made your mind up, it might pay you well.
