So looking on autotrader the prices between Sq5 and Q5 3.0 tdi are basically the same...for some reason tax is cheaper on an SQ5. But insurance is £300 more. Wondering if an Sq5 is worth it over a 3.0 tdi Q5? You do tend to get more spec - electric memory seats for example compared to a Q5. I want a low mileage car to last me 3-4 years. I generally drive lazy I like to waft along but sit high up or I'd get an A8. I guess a Q5 3.0 TDI would be great but a bit worried about DPF problems and S-Tronic problems with a remap if I had the DPF removed. Up here they are making all the motorways 50mph average speed cameras ie "low pollution zones" like the local 3 way highway which means the DPF doesn't cycle on the trip into the city anymore. It's a concern.
