I used my 1980 Plus 8 as a daily commute car from 1987 until 1997. During that time I lived in South Staffordshire and worked in Gloucester, Bristol, Stoke on Trent and Leicester. Racked up 220,000 miles during that time - mainly motorway driving and my petrol bill exceeded my mortgage each month. By 1997 the car was a bit of a wreck - corrosion everywhere as well as wet and dry rot. It then sat for about twenty years before I started the rebuild. There was very little salvageable from the original bodywork other than the cowl. The chassis was scrap as was the bodytub. The engine however was rebuilt and didn't need reboring.
Did make the commute a lot more fun though!
