after owning 2 172's and 2 mk2 dci's id have another dci100 in a heartbeat but not another 172, depends what your looking for in a car though.
i done about 30k hard miles in my dci100, 20k of them remapped at 130hp / 190lbft and had a right giggle in it! abused some much more powerful cars and never had a single mechanical failure until the clutch started slipping at 75k so i traded it in for a GT DCi 106
