The newest from Aston Martin will be a 4 door to compete with the Quattroporte. However, the car will sticker for a higher price than the Quattroporte at $190,000. This will certainly make the car market interesting as more exotics make 4 doors. Slated for 2008.
There is a great test drive article in this weeks AutoWeek. It looks like the car is going to come out to compete with the Quattroporte, Porsche's 4D (althought a Aston Martin is a higher class marquee), and yes...Lamborghini is rumored to have a 4 door coming out.
