Understated
 The "value" of this car is understated in many ways.  It is so much fun to drive, and quite comfortable for an average size person.  On many occasions I have driven 800 miles in a day quite comfortably.  It continues to be reliable, and as it ages, the exceptional and unique design endures.  I believe the 97 2.8 will become a collector vehicle.
