Hi Dave,
Good to hear from you - So many topics that are of common interest and experiences to share.
I was fascinated to hear that you run yours on LPG. !! Keen to hear more, eg availabitity, performane ,issues, modifications etc - obviously it suits you and the primary reason must be oerating costs. Interesting, but would it suit a daily driver, albeit of no more than 5 - 6k miles per year?
Tyres. I bought the car with Avons all round, which were showing signs of age. I replaced them in November 2019 @ 77k miles (4 yrs already !!) after careful reasearch for Falken Ziex ZE-914 Ecorun (£440 for 4 - through Black Circles online).
I have found the tyre to be excellent, i have covered 20k miles in that period, no tread wear or wall damage at all. I chose them (in addition to rain, mpg, noise rating - all good) also for the slightly raised profile to wheel rim, ensuring minimum opportunity for damage to the alloys. I think 6 yrs is tyre life max - as you say regardless pretty much of wear.
Insurance. Do you have an "agreed value" insurance, perhaps through Jaguar Enthusiasts Club, Peter James Classic Insurance. I had been struggling and no one was interested. However, the primary reason I joined JEC was the Insurance deal and have insured mine for a value of £5k, a comprehensive policy including uk/continental breakdown for £210.00.
In the day with three children growing up we had a 1987 Volvo 740 GLE estate auto. We covered Holland, UK and Spain. Fantastic car, 180k miles - needed to refurbish the gearbox, in those days (1992) for £1100.
if you have a handy pic of the S- Type would be interested to see her. i have attached a pic - ignore the low concave on fnt pax dr - all gone now.
Have a good w/e.
Dominic
