Well, the deed's nearly done.
My 9-5's going for close to what I was asking, and later this week I'm collecting a Skoda Octavia, the latest model. It's a 1.4TSi DSG, with 140 horses, 250 Nm, 134 top whack and 0-60 in 8.4. Not bad for a 1.4, and better than the 1.8t that Saab fitted to the 9-3SS. And I'll be paying £30 in VED rather than £285. Should be easier on petrol too. Not new, it's 10 months old with 10k on the clock, but I'm saving around £6k in the process. Standard kit includes parking sensors, bluetooth for phone, dual zone climate control, DAB radio, and lots of other bits. I drove it for an hour and TBH it felt as comfortable as my 9-5. If it can do that for two hours I'll be happy.
It also meets SWMBO's requirement of being smaller than the 9-5 (just!) and will be fine for trips to IKEA. Unlike the Merc I was considering.
As a paid-up member of STT, I'll still be around for a while yet. The advice given by the likes of sgould, Audax, Phoenix, plus many others, has been invaluable over the past nine years, so thanks to all of you. Thanks also for all the light stuff from Norfolk Jim, collywobble, CitTone, plus many more. The tone of conversation on STT is a level above anything else you see on the web; while we sometimes disagree, we always show respect - and those who don't, don't hang around.
I've had my 9-5 for three months shy of nine years. It's cost me an arm and a leg in repairs, you name it, it's been replaced. The Hirsch engine and suspension upgrades were worth every penny. I've spent over £22,700 on petrol, but every mile was a pleasure. Wish me luck with the Skoda.
