running cost calc help anyone?

[ajvmoore]

Hi porsche people - I am visiting from my usual haunt in the TVR postings (sorry - went and said it) in need of help. I am trying to calc the all in monthly cost of ownership (inc depreciation) of two different Porsches - a 996 C4 and a boxster (non S) Both are two years old (early 2001 cars) both fully porsche pampered since new, 996 at 36000 mls, boxster at 28000 mls. The mileage driven will remain similar for the next two years. Anybody help me please?

There are plenty of owners here who could help, if they have the time to work out a precise figure.

You will find both of them considerably cheaper to run than a TVR, with the caveat that you still ought to get a warranty on them as some of the water cooled models have had early teething problems. Go second generation in either model and there is less to worry about.

Remember, Porsche service intervals are every 12k miles, so you halve your servicing costs in an instant (assuming 6k intervals for TVR).

Also, I have seen labour rates as low as 20GBP per hour from specialists that can cater for these cars, so don't be put off by tales of 85GBP per hour main dealer rates unless you need those sought after stamps to keep the history up.

Porsche parts can be expensive, but there are many breakers and many bits are Bosch factor parts, available from Eurocarparts etc.

Mpg is pretty good for these cars, all things considered - the Boxster will be better, of course, simply because it has a smaller capacity engine and less weight.

Depreciation depends strictly on model. Some Porsches do not depreciate, or appreciate (996C4S, older RS models etc.), others depreciate faster than others. You will need to be model and mileage specific.

Hope this helps.

Dom,

Good advice as always.

However, for resale value alone, I'd say servicing on 2001 cars really MUST be carried out by an OPC. The major 48K service on a 996 is only about £475 anyway.

The 12/24K are p*ss cheap.

I think the daily running costs will be about the same, but depreciation won't, the 996 will be higher. May I ask how much each is ? If you are buying from a main dealer you will loose the £5k margin straight off !! For what it's worth I think the BoxterS offers the best value in the Porsche range, the other Boxters are great, but you may not feel happy with their grunt over time !!
An 01 Y BoxterS with low mileage & a decent spec. should be yours for around £30k.
TIP.....phone one of the Porsche buyers & get a trade valuation on your prospective purchase, you will then know it's "real" value !!

As others have said, the major cost (80%)of running a modern Porsche is depreciation. The figure for a 911 is between 6k to 3k per year depending on age for a car that is already 1-2 years old...I went from a 5 year old 993 to an 18 month old 996 and doubled my losses!!...but 996 has turned out cheaper to maintain. If the boxster is cheaper to start with then it will remain cheaper to run. 996 will use more tyre and more fuel and probably more insurance, probably similar service costs. I don't think you can accurately predict what you will buy in for and what you will sell out for some years later, and if you did both transactions with an OPC you better be pessimistic
