Techno cost benefit analysis?

I've been invited to do live set in November at Vondel Bunker in Amsterdam.
I have friends there who will put me up, I know the city well and the venue would pay me in Euros (but only a third of the costs of doing it).
First thoughts oh yes of course!
But, research on trains and ferries shows a total cost of around £250. But I need to MOT my car at the same time.
A live set in Amsterdam would look very cool on Facebook and on my website. The question is: would a gig in a cool Amsterdam club be worth the investment?
My car MOT is really important to me, to drive to local gigs and make my money.
If I had disposable income then definitely yes.
But I don't.
So it's no.
