I think my ZHP is already my modern classic car. I bought my ZHP five years ago and at the time it was replacing my 1991 Alfa 164 as my daily driver. Getting into a rear drive inline 6 with 50/50 weight distribution was like stepping forward multiple generations in automotive handling and dynamics from the Alfa. This in a car that was in absolutely stock form and bettered the Alfa in ever aspect, when I had rebuilt and lowered the entire Alfa suspension with a B&G, Koni, Eibach set up, was the most exciting aspect of the car. The ZHP really is just about close to perfection in stock form. Of course over the years I have also rebuilt the entire ZHP suspension and even added a few M3 goodies and thicker sway bars.
At 110,000 miles I am fortunate enough to have been able to retire the ZHP from daily driver duties and keep it as my project and car show car. I replaced it with a 2013 X1 35i M-Sport. While the X1 is a blast to drive with the 300 horse N55 and X-drive that keeps it firmly planted and is arguably a much better, more modern, and more utilitarian daily driver, it is just not as enjoyable to drive as the ZHP. Honestly, I don't really care what the eventual value of the car is $0 or $100,000 as long as parts, support, and a great community continue to be available I plan on keeping it for my own enjoyment.
