Mines had 5 in total with me being the 5th.. I thought that was a lot!
To be honest, i wouldn't worry about it too much as i did with mine when i got it and really its been great and sure enough i've had to spend some money on it but only maintenance really such as brakes.
To give you real piece of mind, even if your car has just been serviced, i'd maybe service it yourself thoroughly as its not hard even if you've never touched an engine before as there is guides on here, youtube etc.
Look at changing coil packs to R8 ones to upgrade them whilst your on getting messy under the bonnet as a little added extra whilst messing on under there, good quality spark plugs, have a look round the FMIC and check the hoses over to make sure theres no leaks etc, check the diverter valve and PCV valve too and change if needed, i'd recommend changing them though for piece of mind again and there not expensive parts to replace. Theres plenty of threads / guides on here to check things and replace them if need be too so have a look if you haven't already
Then you can drive your car knowing its all fresh under the bonnet and up to scratch
