Advice please!

[Zoso101]

Hi all.

Firstly, apologies for any naivety, but I am brand new to this forum lark.

I would like some input or advice please.

I was always a BM fan, and cherished my E38 730i for a number of yrs, but eventually, it ended up more costly than was practical. After it went, I bought a Ford V6 runabout....but I missed the built quality and the 'umph'. 

Id always liked the look of the Blue IS200, and on a whim, bought one, ON eBay, from South Wales, whilst I was sat on a laptop in Spain!

That was seven yrs ago, and shes been with me ever since. Never been mauled with, and no mods, except 18" Alessio rims, glass blacked from B post back, and roof black vinyl wrapped. 

Shes 16yrs old, yet drives like new, FSH and now 79k

I only do about 7k a yr now because of work and commuting, so its basically free motoring.

My question is this.......

I find myself looking weekly for a 300.

04/05. Seem to go for 3k ish, which doesn't seem much.

Is there any point me swapping?

Or, is there a cost effective way to keep them both?

I appreciate this may be a strange question...but opinions would be appreciated :-)
