The Need for Boost

Hi. Excuse me. I would like to ask something puzzling before I look to buy a Scooby. I would love to travel with a decent Scooby Turbo, a Classic 98-2000 around the UK sometimes, about every month for a day only and perhaps every 6 months to Spain then from there to Morocco then across Morocco from the north to the south, then all the way back to the UK. I would take my time by stopping a night or two in Holland, then stop a night or two in Spain then by ship to Morocco and stop another 3-4 times for a night or two each in various cities inside Morocco. Then would do similar on the way back. so that would be 10 to 13 days total. The question is how do I keep my Turbo from overheating and in good condition? How long does a turbo usually last? How much does it cost to replace one? What are the important maintenance issues that I must watch out for on such journeys? What spares are advised to be taken on a journey? What should be changed before a journey? Please bear in mind that I would keep this car as a spare time car only for weekends. These questions keeping bugging me, so I would appreciate some assistance before buying my next Scooby.
