John, thanks for your sensible advice on Porsche 964 RS investments – you covered a few things I would never have thought of. Will come back to you for an insurance valuation when I find the right car.

Hi John, Thank you for the valuation on my restored Boxster S. Better than I thought! My insurers accepted the valuation in your report without hesitation.

Hi John, I had no preconceived ideas on the value of my 1976 Porsche 911 Carrera, so I really appreciate your excellent service. I will email separately for your insurer recommendations. Best regards, G

Hi John, thank you so much for your valuation, it’s very in depth and I will definitely recommend you to my friends. There’s a few of us that have these kind of unique race cars and it’s hard to get a realistic market value for them. Thanks again.
