Hi and welcome to the forum
While the MGF and TF have a reputation for problems like head gasket failures and other issues, these are in many ways undeserved - if correct attention to maintenance is observed.
Many forum members have one as their daily driver rather than a weekend and bank holiday car.
I personally have no qualms about a drive down to Spain in mine, and many owners frequently go on lengthy Europe trips without issue.
They also have the advantage of having abundant cheap parts, and are relatively easy to work on, unlike more modern sports cars that are pretty much unserviceable by your average spanner monkey home mechanic.
That said, it is worth commenting that many local garages simply don't know how to, or don't want to work on them due to the mid-engine layout as what is a straight forward job in a front or rear engined car becomes a bit of a challenge unless you are a pygmy or a contortionist. This tends to result in anything above an oil change getting a sharp intake of breath followed by a stupidly large quote.
There are however several specialist mobile mechanics who cover pretty much the whole country for work that the owner is not able to do, who charge far less than local garages so this should not be a hurdle as far as buying choices go.
For all lesser DIY jobs there is the wisdom of literally thousands of enthusiasts right here on the forums. It's rare that anyone comes up with a problem that no one else has seen and solved.
The bottom line : hell yes! Go for it!!
