It’s a 2018 Porsche.

Retention of residual value in a car with some of the best residuals in the car market is

Here, in the UK, people put a ridiculous amount of faith in the stamped service book. However, in the US where they are legally allowed to self-maintain their cars without the warranty being compromised, they're not so fussed.
I've bought loads of cars with 'full main dealer service history' to find pollen filters that have never been changed, varnished up engines, wheels that have clearly never been removed and are stuck to hubs etc.
There is only one or two independents local to myself that I would ever trust with my cars. When it comes to dealers, other then Sytner BMW in Swansea, I've had issues with every single one.
