The key thing is of no interest to me whatsoever... In fact I love the starter button in the centre of my dash on my 4.3...
As for exhaust, on the one occassion that I went for a run with a 4.7... I couldn't tell any difference..
If I were buying again, based on my 1 year of ownership, I would still have the same priorities..
Budget. Under £45k and I stuck to it rigidly.... A year ago that eliminated 4.7's from my choice... But if it hadn't, I could just as easily have ended up with one...
Colour.... I was set on blues, greens, dak reds.... Nothing else would do
FSH... An absolute must
Warranty... Not a deal beaker... But would be nice if there was some
Dealer/private.... A personal choice but I much prefer private
Miles..... Less than 20k
Owners..... No more than 2 previous
Interior... Anything but black
Options.... Wasn't really bothered... But I suppose the more the better..
The search started, and after about six weeks a likely candidate turned up, ticked pretty much all the boxes, so that was it
My advice would be don't get to hung up on the differences between models, but concentrate more on what you actually want, then find the car that matches it the closest...
Obviously to do this, you need to know what you want
.... The worst thing is to flit from car to car, not being sure of this or that, because you'll end up making to many compromises.....
Fix your criteria, then go on the hunt
remember for most people, this is a special purchase, so why not make it an enjoyable experience?
I must have got mine right, because a year in, I still love it, and there's nothing I want to upgrade/change..
