I would buy off a forum member if the right Sport was available & more importantly if I had the money - it's about being educated IMO. A warranty is the deal breaker but this can be purchased direct as long as certain criteria has been met 👍
Approved used vehicles don't tend to be over 5 years old & are at least a couple of grand more than the private sellers. 16MY Estoril Blue SVR.............
17MY Autobiography Dynamic - Corris Grey - WOW.
14MY Autobiography Dynamic - SDV6 - Fuji White
12MY Autobiography - SDV6 - Santorini Black - Dual View - Rear Entertainment - Sunroof.
12MY Autobiography - SDV6 - Orkney Grey - awesome ;(
2005 Java Black - 4.2 V8 Supercharged First Edition- will never be forgotten ;(

I have bought several approved used never had to claim on the warranty but peace of mind is always there.
