I agree with all previous posts/suggestions to OP.
Stag is not a suitable first car for 99% of people who just started to drive. A car that's reasonably cheaper, a tad bit older and had a lot of support (from mechanics and more general car community) would be much better for learning in both driving, maintenance and general car knowledge until enough "driving experience" such as car limits, handling different traffic situations, accidents, police attention etc. In the mean time you can also get contacts & connections such as trusty mechanics/workshops, where to buy parts and from which supplier while avoiding the dodgy mechanics, suppliers & stealerships (i mean dealership ).
My 2 cents.
