Welcome ....
2 very different cars mate. Aesthetically very similar if you get a 120 with 180 kit on it - skirts, fogs and straights on a mk1 - same, but 11 spokes on a mk2.
The difference in terms of driving experience is one that's been discussed many times.
A 120 is lighter so some say a better handling car, but the 180 has so much more power and torque with a great roar from the engine it's a personal choice.
Running costs, particularly the insurance is an issue for some. At a rough guess you'll get about 10 more mpg from a 120 and make sure you get a quote for insurance as a 180 is expensive. Tax will set you back £270 for a 180 at least.
Mechanically, the 120 does have notoriety for head gasket failure, but you'll find that many avoid this with a decent service history and/or an upgraded head using a land rover upgrade.
If running costs are an issue and you want petrol - 120 will be cheaper. If running costs aren't so much of an issue - a 180 is a great car.
Don't discount the diesel though. More mpg and a 115 is tunable easily to about 140/150 bhp for about £200 .... and still give you 45+mpg.
Hope that helps - my personal opinions - otherwise there are buyers guides on the site.
