In many ways the Series 1 Roadster is considered to be the pick of the bunch, as others here will no doubt testify.
The more powerful ST220 engine , the Getrag gearbox with appropriate rear axle ratio make for a great drive train.
As you will discover from others the main two watch points are; the very low sump which is vulnerable over speed bumps etc, and the propensity for the axle to tramp under spirited take offs. There are fixes for both, but meanwhile enjoy your new pride and joy.
