S6 is likely not to happen, the potential costs are staggering! Repairing the A6 might, if I can get it as low as it cost me to get the LCR's pickup/pump done, but even then there is a lot of work to do on it in the coming months.
I've got to work out if it's cheaper to trade it in (as is), fix it and sell it, or sell it as-is. Trade in as-is with Audi isn't as bad as I expected (I had it valued today), as obviously they are only knocking off the value of the parts and not the labour, obviously that then ties me in to buying something in their stock, of which there is nothing particularly interesting at the moment. But I'm in no rush. I can drive the LCR in the meantime and leave it there until something does catch my eye in their stocklist.
