Why do you need or want a faster car? You should have more than enough power there to have some fun and cruise quite competently down the motorway. A faster car will only get you into trouble and cost more to own and insure. A faster car will not provide greater entertainment on the road, most likely the total opposite and more powerful front wheel drive cars are going to provide little driving enjoyment even when you can let them loose.
If the Hyundai is boring then I would suggest you either aren't driving it properly or its fat and bloated and dynamically incompetent, probably a mixture of both which doesn't require more power.
I drive a Lada Riva, the reasons why you don't want one are well documented and too numerous to go into, but mostly based on misconceptions. It has got a few things going for it though, it is full of character and is certainly not a common site and it appeals to your sense of humour you can get a lot of car for the money. It cost me £350 for a mechanically sound, tidy car with only one spot of surface rust and only the odd easily rectifiable fault. Insurance was £450 third party with no NCB and 2 years of driving experience, tax is £120 a year (may be worth getting a pre-2001 car for tax brackets). Simple to work on, spare parts are cheap, very tough and it glides over rough roads without a fuss. Apart from being cheap, practical and reliable it also isn't as dynamically incompetent as it first appears with the correct wheels driven, five link rear suspension and a lovely gear change with no faffing about with long linkages it is a great hoot to drive it quickly and has lots of potential to become stupidly quick for what it is with well documented inexpensive modifications.
I'm not suggesting it's the right car for you but think about what you actually want and need from a car. Think about the practicalities of running it, it is easy to assume fuel bills and insurance are the major costs but they aren't necessarily, you've got to consider purchase/resale price, the likely running and servicing costs, will you do the work yourself? Also if you buy a pretty average recent car you could inadvertantely end up paying a fortune in tax. Think outside the box and whatever you do don't just aimlessly go for cars popular with young drivers, the more that drive and crash them the higher the insurance will be.
