Hi, I've decided against the cheaper plug-in option and will now be going for the full ECU remapping as done by Adam of volvo-tuning, see his posts on this forum. He will also upgrade the suspension on all 4 corners of my poor old 850 estate so I'm no longer driving on ROCKS! I'll tell you all about it when it's done, in the next week or two, but am really looking forward to it all.
Diesel is great! I've had diesel Skodas, Mercs, Volvos and would never go back to petrol (as we quaintly call it over here), especially with our prices. Diesel in the US is mostly associated with trucks, vans &c and with gas 1/4 the price it is here, why would any car company bother to market diesel cars there? Diesel car mechanics are as rare as hens teeth in the US anyway. Cadillac tried a few years back with a V8 diesel where first 2, then 4 cylinders cut out as the car gathered speed and momentum, but it was apparently an engineering nightmare and quietly disappeared before long. They are going the dual electric/petrol route now, it seems to me, witness the Toyota Prius which is a roaring success, in Beverley Hills at any rate I'm told you can't afford to be seen without one on your drive ... Enuff !
