A sort of update to my above post.
Saturday we headed off in the Toledo towards Suffolk via Essex and Diss....
Gill, my long-suffering wife, commented on how relaxed the car was as we zipped up the motorway at 85. She reckoned it felt very good, unstressed and the only downside was wind noise from the front windows.
We stayed with friends afer various visits, and Sunday did the CT navigational rally, some sections were on very bumpy surfaces, but the car behaved impeccably. We came 4th, not too far off the winners (couple of small errors plus a driver who missed a few codeboards....)
We them travelled to Cromer to stay with friends, and today travelled back in pretty awful weather. But we made VERY good progress, and the Michelin Crossclimates again proved to be very capable tyres (smallest size is 14" though). I reckon we averaged around 35mpg over the nearly 500 miles covered. 2 small issues. Te fuel pump gasket seems to be the source of an oil leak, must replace that. And the starter needs to come out to fix the occasional inability to start. I think it is the connections inside the solenoid, it clicks but won't even attempt to spin, but usually will go after numerous attempts, then is fine for ages....
Maybe the car will live longer than I thought if it continues to behave so well
